Astronauts spend their time on the International Space Station working on science experiments that can only be done in zero-gravity. But it’s not just hard work and number crunching. In this new video by NASA’s Marshall Center, a group of astronauts create a large bubble of floating water and then put a waterproof GoPro camera inside it. You know, for science!

While serving on the International Space Station, Expedition 38 crew members took a break from work to marvel at the Earth. From their unique perspective, they were able to point out many famous cities across the globe. Simply awe inspiring.

“The goal with this sequence was to bring a bit more attention to the station itself, including the humans aboard it, particularly Don Pettit (appearing in the final shot) who took many of the sequences in this montage.”

Lucky for nerd viewers, astronaut Karen Nyberg is on the ISS has apparently stepped forward to fill the void. In her debut short film, she demonstrates for viewers how one washer their long hair in Space. Naturally it’s a lot more difficult to execute than on Earth.
